the examples below show some of the many control applications ITI has
undertaken...

Fuel Processing Machine

In this application, we undertook to design a machine to process saw
off-cut of several meters into a format that could be handled more
efficiently and would be suitable as gasification fuel. The machine shown
is a fully self-contained system that processed more than 1 Tonne of
material/hour. In a control application of this scale, the PLC's baby
brother, the Smart Relay was used. This was programmed to monitor
analogues such as hydraulic oil temperature and pressure and digitals
Such as start and stop buttons. The Smart relay even logs the run time
and material jams for maintenance purposes.

PLC Press Control System

At Moyola Industrial Repair , a 20 year-old 200 ton hydraulic press
was overhauled to include a PLC control system that increased its
throughput and safety systems

PLC Controlled Punching Machine

A
new punching machine was designed and built for Sperrin Metal Products
Ltd, including a PLC control system. The operation of the old machine had been controlled by hydraulic
pressure switches - a slow and maintenance-hungry system. Once installed,
the new PLC
controlled machine improved the throughput by up to 60%.

PLC & Touch Screen.

A PLC control system equipped with an touch screen (HMI) offers a very
effective interface between operator and machine, allowing operational
adjustments and monitoring the system during use. An example of where
this system has successfully been used is in the control of a locally
designed Mushroom Grading machine. The machine is now being used by some
of the UK's biggest growers and is a unique solution to making
growing houses more efficient in a very competitive business.

ITI use the following PLC manufacturers regularly, though
alternatives can be considered as required by project or client.
